Spot on my grass? I just planted new fescue grass more or less a month ago...

I just planted new fescue grass more or less a month ago and finally got it looking great. This morning when I left the house everything looked everyday. This evening when I got home there be a big spot (about 2 feet by 2 feet) where the grass have turned the color of straw. Im trying to find out what is causing it. My 2 thought are 1) dogs. I dont have any but the neighbors simply cant seem to keep their dogs on their own property. 2) a friend of mine come over day before yesterday and pulled into the patio, I think about indistinguishable place as this spot. Could anything have leaked from her motor that would do this? I mean, her car is within good condition, I was basically wondering. Basically I want to find out what caused it so I can try to keep it from going on again. Also, is there anything that I can do to repair the spot?? Any thought or ideas would be great! Thanks!
Dog urine is a possibility, but my experience has been that it take longer then a few hours for the grass to get adjectives. Grubs are also a possibility because their damage is visible during the hot dry period which is when the grass is under pressure. It could also be chemicals from the car. If it is grubs you will know how to roll the area up like a hearth rug, however if you have grubs this sort of spot would be seen adjectives throughout the lawn not just contained by one spot. To repair the spot you will have to remove all the unmoving grass, I'd recommend removing the first few inches of dirt as well and replacing it with angelic topsoil because if it was a chemical from a car the soil is infertile and grass won't grow


Sounds like dog urine. Only way to fix it is to replant the grass and keep hold of the dogs away. grubs! try a grub treatment.
Answers:    Okay, lots of possible cause but I think you have already told us the answer...
Dog urine can burn spots into the meadow, particularly female wee as the girls tend to budge in one spot not all over the place. This is because the urine is resembling a concentrated fertiliser & is too strong for the lawn. The give-away that it's dog wee doing the damage is that on the exceptionally edge of the circle the grass will be very green, lush & taller. Why is this I hear you ask? Well, at this point the urine be at the 'right' concentration to work as a fertiliser & not scorch! A urine spot is unlikely to go brown surrounded by just one day unless the weather been really hot & dry.
Lawn grubs or worms of the various sorts can mete out dead spots. Not often are these clear, verbs spots. Also not often will they brown so quickly, that would mostly take quite a few days. There are some grubs that can wreckage seemingly overnight but they are more likely to leave a exposed or thin patch, not dry straw-like grass as you describe. The give-away for grub damage is if you grasp a clump of the dead grass & it easily lift away from the soil its grubs as they've chewed off all the roots.
Some fungal disorders can create spotting, but again not so quickly & more likely within damp & humid weather.
Soooooo. that brings us back to what contained by this case is I think the expected cause... I think it's the sports car that has done it! (not the butler...)
Possibly hot liquid dripping (like radiator overflow) but more feasible radiant heat from the transmission, engine block or exhaust system have basically cooked it.
This would be more likely next to a car low to the ground or where a rise surrounded by the lawn or drive cause cut of the car to sit close to the grass.
This really is the most likely explanation for the grass browning so vigorously.
